Abstract
Disclosed is a power supply unit, PSU, for wirelessly powering components of a radio base station, RBS, such as a radio unit, RU, transmission units (TMR) and a baseband digital unit, BDU. The PSU includes a TX coil for generating an energy field that is used to induce a current and voltage in an RX coil that is part of a component of the base station. The need for power cables, which are inefficient at transferring energy, is therefore greatly reduced. Hence, the energy efficiency of the RBS is increased.
